My invention relates to improvements in emergency sections for ships,and it consists in the combinations, constructions and arrangementshereinafter described and l! claimed. v

An object of my invention is to provide an emergency section for shipsthat has accommodation for all of the people carried by the boat andenough storage space for food and equipment to take care of the peopleuntil rescued. The section is made strong and is secured to the ship insuch a manner that it will float free if the ship should sink. It alsohas means for permitting the section to be launched when the shi haslisted but not as yet sunk.

further object of my invention is to provide a device of the typedescribed that makes use of a roller chain for permitting the section toeasily slide ofi from the ship,

either end of the chain being releasable from the section so as to havethe chain permit the section to move, and subsequently to have the chainhang downwardly and act as an anchor for the section. The listing of theboat aids in the launching of the section, whereas with the usuallifeboats the boats on the weather side cannot be readily launched.

Other objects and advantages will appear as the specification proceeds,and the novel features will be particularly pointed out in the appendedclaims. I

My invention is illustrated in the accompanying drawing, inwhich Figures1 and 2 show perspective views of boats with the emergency sections inplace;

Figure 3 shows a boat with a thirty-degree list, and further shows howthe section is inclined so as to readily move into the water; w

Figure 4: is a top plan view of the emergency section; Figure 5 is afront elevation;

Figure 6 is an end elevation;

Fi ure 7 r 's a sectionalong the line 7-7 of Flgure 4; and 1 Figure 8 isa section along the line 8-8 of Figure 6.

In carrying out my invention, I show an emergencv section at theposition A on the boat 1. The boat shown in Figure 2 carries twoemergency sections B, one fore and oneaft. It is obvious that thesections may 5 be placed at any desirable point on the boat so as to notinterfere with the normal use of the boat yet be ready to receive all ofthe people and carry them to safety in case of the sinking of the ship.

In Figure 3 I show a boat 2 as listing to an angle of thi'rty degrees.It will be seen that the lifeboats 3 on'the right-hand side of the boatcannot possibly be launched without sliding down the side 4: of theboat. This will cause the lifeboats to either upset or possibly bedamaged before nearing the water. In the same Figure 3 I show anemergency section indicated at C. The section is made large enough tocarry all of the passengers, and it will be seen that the inclination ofthe boat will not interfere with the proper launching of the section butin fact will aid it. v

I will now describe the particular construction of the section.Reference to Figure 4 shows that the section is rectangular in shape,although any other shape may be resorted to without departing from thespirit and scope of my invention. The section has a roof 5, a bottom 6,sidewalls 7 curved end walls 8, a railing 9 on the top wall, and anentrance hatch 10 (see Figure 3). The hatch may be closed, and this will7 keep out water even though the waves dash entirely over the section.Of course, the section is made strong enough to withstand the buffetingof the waves and to'safely carry all of the'people until rescue comes.

The section is held in place by locking members that may be manuallyreleased. I further provide an automatic release should it be impossibleto release the section before the ship sinks. The section is locked ateach end and along each side. The locking mechanism at each end and sideis identical, and therefore the description of one will sufiice. a

In Figure 4 I show the deck 11 of the boat. This deck carries an endp1ate'12 W9 preferably having a length equal to the width of thesection. The plate 12 is hinged at 13 to the deck, and its upper edgeshingedly carry retaining members 14 (see Figure 4). The members 14 restupon the top 5 of the section, and have openings 15 for receiving lugs16 formed as extensions from the sides 17. Figure 4 shows two sides 17as cooperating with each end 12. So long as the members 14 remain in theposition shown, the'plate 12 and sides 17 will be interlocked and theemergency section will be held in place.

I provide means for manually releasing the plate 12 from the sides' 17 Alever 18 (see Figures 4 and 5) is rigidly-connected to a cross shaft 19,the latter being mounted in bearings 20 carried by the top '5. At theends of the shaft 19 I dispose lifting members 21. These membersunderlie the members 14 as is clearly shown in Figure 7, and when theleft-hand lever 18 is swung clockwise in Figure 5, the left-hand members14 will be swung about their hinges 22 and will release the sides 17from the end plate 12. The end plate 12 will swing about its hinge 13 asindicated by the dotted line in Figure 3, and the sides 17 will swingdown upon the top 11. This will clear the deck for the move- .ment ofthe section toward the left in Figure 5. If the boat has listed in themanner shown in Figure 3, the section will start to move when theleft-hand end of the chain is released.

I have provided a roller chain between the emergency section and thedeck 11 for permitting the ready movement of the section into the water.The rollers 23 are connected to each other by links 24 (see Figures 5and (3). Either end of the chain may be released. This will permit thechain to hang downwardly from the opposite end after the section reachesthe water, and the chain will act as an anchor. If the angle is not toosteep, the section will be held in place by the chain until the end ofthe chain on the lowermost end of the section is released.

In Figure 8 I show a lever 25 that is secured to a rod 26, the latterbeing carried by bearings 27 that in turn are supported by the emergencysection. The rod has hooks 28 and the lever has a similarly-shaped hook29 that extends beneath the shaft '30 upon which the end set of rollers23 are mounted. The lever 25 may be swung after the end 12 has beenreleased, and this will free the end of the roller chain. This end ofthe chain will dropdown upon the deck 11 and will permit the section tomovefreely thereover. After the section reaches the water, the chainwill hang downwardly from the other end and will act as an anchor.

In case the boat sinks. so rapidly as to prevent the actuation ofeitherof the levers 18 or 25, the section will automatically releaseitself. It will be noted that the section will float upwardly away fromthe deck 11 should the boat sink, and this will lift the members 14 offfrom the lugs 16 for freeing the end plates 12 and the sides 17. Thesection may now float away independently of the boat.

It should be noted that the section will not move even though theretaining plates are freed. The chain must first have its lowermost endreleased before the section can move.

Although I have shown and described one embodiment of my invention, itis to be understood that the same is susceptible of various changes, andI reserve the right to employ such changes as may come within the scopeof the invention as claimed.
